TheErebus class of warships was aclass of 20th centuryRoyal Navymonitors armed with a main battery of two15-inch /42 Mk 1 guns in a single turret. It consisted of two vessels,Erebus andTerror, named after the two ships lost in theFranklin Expedition. Both were launched in 1916 and saw active service in World War I off the Belgian coast. After being placed in reserve between the wars, they served in World War II, withTerror being lost in 1941 andErebus surviving to be scrapped in 1946.
